(a) Assuming the inputs and output terminals are at 0-V dc in Fig. P5.14, estimate the smallsignal gain a 5 voy(vp 2 vn ). Assume 0 5 100 and VA 5 ` for all BJTs, and ignore base currents during your dc calculations. (b) Using matched pnp BJTs, design a circuit to provide the 0.1 mA and 1 mA bias currents.
